Human Skeleton
The human skeleton is an interesting but complex structure. An adult human has 206 bones. At birth, we all have 300 ones but they fuse together over time as we grow. Our skeletal system does more than helping us to hold the shape of our bodies. It also provides protection to internal organs, produce new blood cells, assists in body movement, endocrine regulation etc. Although our teeth are considered as a part of the skeletal system but they are bones. The medical study of human bones is called orthopaedic.
